Agricultural and Forest Entomology, EarlyView.Ethanol‐baited traps were placed in cultivated chestnut orchards (a) and mixed environments with assorted tree composition (b), over a 2‐year monitoring period in two valleys (NW Italy). A total of 118,286 ambrosia beetles was collected, representing six species.

Agricultural and Forest Entomology, EarlyView.The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Agricultural and Forest Entomology, EarlyView.The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Boreas, EarlyView.Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Ecological Entomology, EarlyView.Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.
